Andreas Straub 909f761ca1 Refactor axolotl message processing workflow ... XmppAxolotlMessage is now entirely responsible for handling encryption and decryption of messages, only leveraging XmppAxolotlSession as a packing/unpacking primitive for payload keys. Removed pseudo-dead session generation code step from prepareMessage function, as sessions have been created by invoking the TrustKeysActivity for a while now. Added prepareKeyTransportMessage function, which creates a message with no payload. The key that is packed into the header keyElements can then be used for other purposes (e.g. encrypted file transfer).		2015-07-31 21:31:45 +02:00
